Embodiment 1

[0073] Such as Figure 1-2 As shown, this water-based eco-solvent diamond canvas includes:

[0074] The substrate layer 1 is made of any one of chemical fiber, flax and paper;

[0075] The graphic layer 2 is arranged on one side of the substrate layer 1 and the graphic layer is an anti-stretch / shrinkage coating; the graphic layer 2 is made by mixing acrylic resin and polyethylene solution; or by mixing PU resin and polyethylene solution production.

[0076] The bottom layer 3 is arranged on the other side of the substrate layer 1, and the composition of the bottom layer 3 is:

[0077] Resin 29-31 parts;

[0078] 29-31 parts of water;

[0079] Filling 29-31 parts;

[0080] additive;

[0081] The components of the filler are:

[0082] 4-6 parts of titanium dioxide;

[0083] 15-50 parts of calcium carbonate;

[0084] 8-12 parts of silicon dioxide;

[0085] Titanium dioxide can improve the hiding rate.

[0086] The surface layer 4 is arranged on the side of the bottom lay...

Embodiment 2

[0141] The structure and principle of this embodiment are basically the same as those of Embodiment 1, so they will not be repeated here. The difference lies in:

[0142] The bottom layer 3 is arranged on the other side of the substrate layer 1, and the composition of the bottom layer 3 is:

[0143] 29 parts of resin;

[0144] 29 parts of water;

[0145] Filling 29 parts;

[0146] additive;

[0147] The components of the filler are:

[0148] 4 parts of titanium dioxide;

[0149] Calcium carbonate 16 parts;

[0150] Silica 9 parts.

Embodiment 3

[0152] The structure and principle of this embodiment are basically the same as those of Embodiment 1, so they will not be repeated here. The difference lies in:

[0153] The bottom layer 3 is arranged on the other side of the substrate layer 1, and the composition of the bottom layer 3 is:

[0154] 31 parts of resin;

[0155] 31 parts of water;

[0156] 31 parts of filler;

[0157] additive;

[0158] The components of the filler are:

[0159] 6 parts of titanium dioxide;

[0160] 17 parts of calcium carbonate;

[0161] Silicon dioxide 8 parts.

Abstract

The invention belongs to the technical field of canvas, and in particular relates to a water-based weak solvent diamond canvas and its preparation process. It solves technical problems such as poor practicality of existing technologies. This water-based eco-solvent diamond canvas includes a base material layer, which is made of any material such as chemical fiber, linen and paper; a graphics layer, which is set on one side of the base material layer and the graphics layer is an anti-stretch / shrink coating; the bottom layer, which is set On the other side of the base material layer; the surface layer is placed on the side of the bottom layer away from the base material layer. The preparation process of this water-based weak solvent diamond canvas includes the following steps: A. Preparing materials; B. Coating. The advantages of the present invention are: 1. The design is more reasonable, the anti-stretch / shrink ability is strong, and the service life is extended. 2. The covering rate is good, the minimum amount of paint used to make the background color no longer show up, beautiful and practical. 3. It has strong ink absorption capacity and is more practical. 4. The process is simple and easy to control, which is in line with the current development trend of social technology.

Description

technical field [0001] The invention belongs to the technical field of canvas, and in particular relates to a water-based weak solvent diamond canvas and a preparation process thereof. Background technique [0002] Canvas: The cloth used for painting oil paintings, usually yellow-brown linen, but also cotton and chemical fiber cloth. The existing canvas has the following problems: poor anti-stretching / shrinking ability, resulting in damage to the pictures on the canvas; secondly, poor coverage and impractical. [0003] In order to improve the existing technology, for example, the Chinese patent literature discloses an ink-absorbing dry canvas, [application number: 201310679748.4], the preparation steps are: apply the clear glue to the surface of the fabric, and then heat it in an oven at a temperature of 100-120°C Drying at low temperature to obtain the clear glue layer; then the primer is applied to the surface of the clear glue layer, and then dried in an oven at a temper...
